H EEL-ATTACHING MACHIN E.

SPECIFICATION forming part of Letters Patent No. 394,298, dated December1l, 1888.

Application filed April 27, 1888. Serial No. 272,023. (No model.)

To all whom t1/my con/cern:

Be itknown that I, FREEBORN F. RAYMOND, 2d, of Newton, in the county ofMiddlesex and State oli' Massachusetts, a citizen of the United States,have invented a new and useA ful Improvement in lIeelU/XttachingMachines, otA which the following is a t'ull, clear, and exactdescription, reference being had to the accompanying drawings, forming apart of this spcciiicatiomin explainil'lg its nature.

The invention relates especially to devices for attaching a `French orogee heel. French or ogee heels have generally been attached to thesoles of a boot or shoe in two parts or divisions by successive nailingoperations, although they have also been secured by aI single gang orgroup of nails driven from the tread end of the heel, which nails arecaused to take an outwardly-inclined path as they are driven b v firstforming outwardly -inclined awl-holes. By my invention the heelblank isattaclled by nails driven sim ultaneously, some ot which are driven fromthe tread end of the heel-blank and some from the riser or iirst sectionof the blank. The heel-blanks for French heels are usually made in twoparts-viz., the seat-section and the tread-section. The seat-section isusually considerably longer than the treadsection, and the object ofmaking the blanks in two parts is to save stock and to facilitate theattaclr ment where they are secured in successive order. These sectionsare sometimes called decks.

To carry my invention into effect, I employ a templet which has twolevels or bearingsurt'aces, one ot' which rests against the outersurface of the lower deck or section and the other of which against thesurface of the upper deck or the tread end of the heel; and I alsoemploy awls carried by the same plate or head, but preferably varying inlength, the longer being adapted to form the holes in the lower deck andthe shorter the holes in both decks, but extending from the uppersurface of the upper deck. I also use drivers carried by the same plateor head to be operated simultaneously, but which varyin length, thelonger of which are adapted to drive the attaching-nails into the lowerdeck, and preferably sufticiently below the level thereot` as to leavethe heads out of the path of the heel trimmer or cutter. The shorterdrivers are adapted to drive the nails through both decks either [lushwith the upper surface of the upper deck or t0 extend therefrom forblindnailing the top lift.

In the drawings, Figure l is a view, part in section and part in sideelevation, ot' the central and upper parts oi a heel-nailing machinehaving my improvement. Fig.4 2 is a view, part in front elevation andpart in cross vertical section, ot' the central and upper parts of aheel-nailing machine to ['urther illustrate my invention. Fig. 3 is aplan view of the templet and nail-carrier. Fig. i is a plan view of asection of a templet, to which reterence is hereinafter made. Fig. 5 isa view in vertical seetion of a portion of a shoe and heel,

representing in dotted outline the heel-blank t before it is trimmed.Fig. 6 is a view in plan inverted of an ogee heel and a section of thesole of the shoe to still further.illustrate the operation of theinvention.

Arepresents thelasterwork-support; u, the slide-jack, upon which it ismounted; o', the bed of the machine upon which the jack is arranged toslide.

l), is a table, which, preferably, is provided wit-h a vertical movementupon a post, b, in opposition to spring-pressure, and which has aslideway in which is secured the templet (l, and which, preferably, ishorizontally movable therein.

D is the nail-carrier.

E is the cross-head, which is reciprocated preferably substantially asdescribed in Patent No. 310,894. It carries a revolving head, e, havingradiating arms, one of which supports the gang orgroup of awls e',another the gang or group of drivers e2, and the third atop-lift holderand spanker, c3. The templet C comprises the imperforate section c andthe section c', which is provided with the holes c2. The templet alsohas the section or part c3, having' the curved Vface c1l and holes c5,which are in continuation of the holes clot the plate. This section c3has a pressing or bearing sul face, c, upon a lower or different levelthan the pressing or bearing surface ci of the main part of the templet,and it is adapted to bear against the upper surface of the lowerheeldeck. lVhile it may be made integral with the templet C, it ispreferable to make it detachaloo the nails.

ble, in order that sections of greater or less height for use withlonger or shorter heels may be substituted, and in Fig. l of thedrawings I have represented it as made a separate piece and secured tothe templet by the screws e8.

It will be seen that the templet C has the line of holes c2, throughwhich the nails which are driven through both decks of the heel are fedor delivered to it, and the line of holes c5, which delivers nails tothe lower deek of the heel only. The awls e may be of the same length;or, if desired, those which operate to prick the lower deck only maybemade somewhat longer than those which prick both decks. The gang c2 ofdrivers has the short drivers e4, which drive the nails through theholes e2 of the templet into the upper deck of the heel-blank, and thelong drivers e5, which drive the nails through the holes c5 into thelower deck of the heel-blank, and which, preterably, are long enough toextend below the bearing-surface e when in their lowest positionl toenter the vlower deck of the heel-blank and drive the nails any desireddistance below said surface, so as to leave sufficient stock to beremoved in shaping the heel without striking the heads of thenails. Oi'course the trimmedheel-blank will have holes midway its height before itis finished; but these holes are filled with suitable iilling in thefinishing of the heel-blank.

In use the boot or shoe is placed upon the last or work-support, thelower section or deck placed upon the heel end of the outsole and sothat its rear section extends under the surface cj ot' the templet, theupper deck is placed so that its edge bears against the curved front c4of the lower section, ci, of the templet, and the table B and templet Care then moved downward, the heel-blank clamped upon the boot or shoe,and while thus held it is pricked by the reciprocation of the awls whichform the holes f in the lower deck and also the holes f in the upper andlower deck simultaneously. The attaching-nails are then fed to the holesc2 c5 of the templet by the nail-carrier D,which has a like arrangementof holes for holding Longer nails, however, are fed to the holes c2 thanto the holes ci?, as it is necessary that they should extend through theupper and lower decks into the soles of the boot or shoe, while theother nails extend only from the lower deck. The drivers are thenbrought into position and reciprocated, and the long and short nails aresimultaneously driven, the long nails through both decks into the solesof the boot or shoe and the shorter nails into the lower deck and solesof the boot or shoe, the heads of the shorter nails being driven,preferably, below the surface of the deck, as represented in Fig. l, bymaking the drivers extend below the surface c(i of the templet. Thisbrings the heads of these nails below or within the iinished line of.the heel. (See Fig. 5.)

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United Statesl. In a heel-attaching machine, atemplet for driving nails at different levels, having the bearing orpressing surface "cf", the bearing or pressi-ng surface e7, and theholes c2 c5, substantially as described.

2. The combination of the templet having the holes c2 andpressinosurface c7 with the removable section c3, having the holes e5,substantially as described.

The combination of the templet C, having the holes e2 c5, the sectionc3, having the bearing-surface c, and the front curved edge, c4, andholes c5, substantially as described.

il. The combination of the last or work-support, the templet having thebearing-surfaces c c7, the holes ci c2, with'the gang otv awls to enterthe holes c2 and a gang of drivers to enter said holes, and comprisingthe group of short drivers eL1 and the group of vlong drivers e5,substantially as described.

5. The combination of the last or work-support, the templet having thetwo bearing-surfaces cG c7 at diil'erent levels, and holes c2, extendingto the one level, the holes c5, extending to the other level, and a gangof drivers in two groups, the shorter of which are adapted to drivenails through the shorter holes and the longer of which are adapted todrive nails through the longer holes and to exten d below the ends ofsaid holes to drive nails below the level of the deck of the heel,substantially as described.

(5. The combination, in a heel-nailing machine, of a templet havingholes c5 with a gang of drivers of a length greater than the length ofthe holes, and suitable operating mechanism for reciprocating thedrivers to bring their driving ends below the ends of said holes, as andfor the purposes described.
